Product details
Overview
74AVC8T245PW,118 from Nexperia is an 8-bit dual-supply translating transceiver enabling bidirectional level translation between 0.8 V and 3.6 V domains. It features independent VCC(A) and VCC(B) supplies, DIR-controlled direction, OE-enabled 3-state outputs, and IOFF circuitry for partial power-down. Used in mixed-voltage SoC interconnects, such as FPGA-to-ASIC data buses requiring voltage domain isolation.
For engineers reviewing the 74AVC8T245PW,118 datasheet, 74AVC8T245PW,118 pinout, 74AVC8T245PW,118 application, or 74AVC8T245PW,118 equivalent, key selection criteria include configurable voltage translation range (0.8–3.6 V per rail), maximum data rate (380 Mbit/s), suspend-mode behavior, and TSSOP24 package thermal performance at +125 °C.
Technical Context
The device implements a dual-rail CMOS transceiver architecture with separate input reference domains: An, DIR, and OE referenced to VCC(A); Bn referenced to VCC(B). Direction control is synchronous and non-latched-signal flow follows DIR state in real time without internal storage.
IOFF circuitry actively disables outputs when either VCC(A) or VCC(B) is at GND, preventing backflow current and ensuring high-impedance isolation during suspend mode. ESD protection meets ANSI/ESDA/JEDEC JS-001 Class 3B (8 kV HBM) and JS-002 Class C3 (1 kV CDM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range (VCC(A)/VCC(B)) | 0.8 V to 3.6 V each - enables translation across 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic nodes |
| Max Data Rate | 380 Mbit/s - achievable when translating ≥1.8 V to 3.3 V, supporting high-speed parallel bus interfaces |
| Propagation Delay (An→Bn) | 2.7 ns min / 9.9 ns max - measured at VCC(A)=3.3 V, VCC(B)=3.3 V, -40 °C to +125 °C |
| IOFF Leakage Current | ±1 μA max - ensures <1 μA backflow during partial power-down, critical for system-level power gating |
| Operating Temperature | -40 °C to +125 °C - qualified for automotive under-hood and industrial control applications |
| ESD Protection | HBM >8000 V, CDM >1000 V - exceeds JEDEC standards for robust board-level handling and field reliability |
| Input Voltage Tolerance | Accepts up to 3.6 V on all inputs - allows safe interfacing with higher-voltage signals even when VCC(A) is low |
Pinout & Package
TSSOP24 package (SOT355-1), 4.4 mm body width, 0.65 mm pitch, 24-lead plastic thin shrink small outline. Pin 1 index located at top-left corner; GND pins (11, 12, 13) require connection to 0 V reference.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC(A) | Supply A | Reference for An, DIR, OE inputs; sets input threshold and output drive strength on A-side |
| DIR | Direction Control | HIGH enables An→Bn flow; LOW enables Bn→An flow - no internal latching, real-time control |
| OE | Output Enable | Active LOW - asserts high-impedance on both ports when HIGH, isolating A and B buses |
| A1–A8 | Data Port A | Bidirectional I/O referenced to VCC(A); supports 8-bit parallel data transfer in either direction |
| B1–B8 | Data Port B | Bidirectional I/O referenced to VCC(B); electrically isolated from A-side supply and thresholds |
| VCC(B) | Supply B | Reference for Bn inputs/outputs; independent of VCC(A), enabling asymmetric voltage translation |
| GND (11,12,13) | Ground | All three must be connected to 0 V - ensures stable reference and minimizes ground bounce in high-speed operation |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply rails | VCC(A) and VCC(B) operate independently from 0.8 V to 3.6 V - eliminates need for external level shifters in mixed-voltage systems |
| IOFF partial power-down | Outputs disable automatically when either supply drops to GND - prevents back-current and enables safe hot-swap or sleep-mode sequencing |
| Suspend mode isolation | Both An and Bn enter high-impedance OFF-state when VCC(A) = GND or VCC(B) = GND - guarantees bus decoupling during power loss |
| JEDEC-compliant voltage standards | Meets JESD8-12 through JESD8-B across full voltage range - ensures interoperability with industry-standard low-voltage logic families |
| High-speed timing performance | Sub-3 ns propagation delay (An→Bn @ 3.3 V) and <12 ns enable/disable times - supports >300 MHz clocked parallel interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply translating transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC8T245RHLR | VQFN24 package (3.5 × 5.5 mm), lower thermal resistance (42 °C/W vs. 110 °C/W), rated only to +85 °C | Better suited for space-constrained consumer electronics with moderate thermal loads; not qualified for automotive or extended-temp industrial use | Select when board area is critical and ambient temperature stays ≤85 °C; avoid where +125 °C operation or TSSOP reworkability is required |
| 74LVC8T245PW,118 | Single-supply operation (1.65–3.6 V), no VCC(B) independence, lower max speed (240 Mbit/s), identical TSSOP24 footprint | Limited to same-voltage-domain translation; cannot translate 0.8 V ↔ 3.3 V or support asymmetric rail sequencing | Choose only for cost-sensitive designs where both sides share a common supply and speed <240 Mbit/s suffices |

FAQ
Can 74AVC8T245PW,118 translate between 0.8 V and 3.3 V simultaneously?
Yes. VCC(A) may be set to 0.8 V (for 0.8 V logic interface) and VCC(B) to 3.3 V (for 3.3 V logic interface), enabling true bidirectional translation. The device supports this combination across its full -40 °C to +125 °C operating range with verified timing and IOFF behavior.
What happens to the outputs when VCC(A) = 0 V and VCC(B) = 3.3 V?
In this suspend condition, both An and Bn ports enter high-impedance OFF-state regardless of DIR or OE state. IOFF circuitry blocks back-current from Bn into the unpowered A-side, protecting downstream 0.8 V or 1.2 V circuitry from damage or false logic states.
Is the TSSOP24 package lead-free and RoHS compliant?
Yes. The 74AVC8T245PW,118 uses a lead-free, halogen-free, RoHS-compliant TSSOP24 package (SOT355-1) with matte tin finish. It meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) and is compatible with standard SnPb and lead-free reflow profiles.
How does OE interact with DIR during direction switching?
OE operates independently of DIR. When OE is HIGH (disabled), both ports are in high-impedance state regardless of DIR value. When OE is LOW (enabled), DIR determines direction in real time-no setup/hold timing is required between OE assertion and DIR change.
